The invention relates to a new technique method for treating and repairing the defects of a hollow shaft of a coiling machine with steel or reforging the hollow shaft of the coiling machine with steel. The technique method solves a series of technique problems such as material selection limitation, large thermal stress during the technique process, large thermal deformation, coarse material grains, poor bonding strength of matrix material, great effect of thermal welding processing on the mechanism performance of the base material, and the like. Both a laser cladding composite layer and the matrix have no coarse structure, a cladding layer and a base interface have compact structure and fine grains and the cladding structure has no crackle, inclusion and other defects; the cladding layer and the matrix form alloy combination and do not fall off; the thermal deformation is small, the stress is low and the surface hardness is high; the matrix dilution ratio is low, the size and position of the cladding layer can be controlled precisely, the mechanical finishing allowance after cladding is small, and the composite functional layer is characterized by high corrosion resistance and high abrasion performance. The method does not pollute the environment, has high production ratio and low energy consumption and greatly reduces the fittings consumption cost of enterprises.
